IPC: G01N1/22
Filed: 1979-03-16
Abstract: PURPOSE: To improve the measuring efficiency and prevent a worker from being exposed to radiant rays, by charging and recovering a sample without breaking vacuum in a furnace tube, whereby the time for measuring evaporable impurities in the sample can be shortened.  
     CONSTITUTION: A sample is introduced into a feed mechanism 12 from an inlet 11. The inlet 11 is then closed to open a valve 9 so that the sample in the feed mechanism 12 enters a sample receiving section 10. The valve 9 is then closed. The pressure in the measuring system as a whole is reduced by a pump 18. The measuring system is made highly vacuous by operating pumps 26, 27, 29, and a furnace tube 3 is subjected to vacuum burning by heating the same at a high temperature by a heater 4. Valves 30, 36 are closed and pumps 40, 42 are operated to conduct measurement of blank gas with a pressure gauge 38. The valves 30, 36 are then opened to discharge the gas collection section 37. The valves 30, 36 are closed to introduce the sample in the sample receiving section 10 into a sample holder 25 in a Mo cylindrical furnace 2. The sample is heated at a high vacuum and a high temperature. The impurities in the gasified sample are collected in the gas collection section 37 by pumps 40, 42 and subjected to measurement.

Abstract: PURPOSE:To compensate the high band component of the jitter, by detecting the high band error signal on the basis of the output of an oxcillator synchronizing with an input signal and then mixing this signal with a phase error signal that controls the transfer time of a CCD. CONSTITUTION:The input signal containing the jitter and supplied from a video signal input terminal 13 is applied to a CCD14, a horizontal synchronous separating circuit 15 and a burst signal separator 16 respectively. The synchronizing signal containing no jitter and supplied from a reference synchronizing signal input terminal 17 is applied to a phase comparator 18 along with the separated synchronizing signal to obtain a phase error signal. On the other hand, the separated burst signal is led to a flywheel circuit (PLL circuit) 22 consisting of a phase comparator 20, a low pass filter 23 and a voltage control oscillator 24. Thus the high frequency component of the jitter is delivered as a high band phase error signal. These both phase error signals are mixed and supplied to a voltage control oscillator 21 to control the frequency of the transfer clock signal of the CCD14.

Title: Sphygmomanometry method
Inventor: OMORI KENJI
IPC: A61B5/022
Filed: 1992-01-21
Abstract: PURPOSE:To measure a blood pressure value as absolute pressure in arteries with proper precision by using a surface pressure sensor which gives push- pressure to the arteries on an organism surface. CONSTITUTION:In the process of squashing a radial artery by gradually increasing push-pressure of a surface pressure sensor, the sensor continually outputs a pressure signal SM, which includes pressure pulses. A first straight line (a) and a second straight (c), which are formed of curves connecting the upper peak of each pressure pulse, cross at an intersection point (e), and on the basis of the point (e) a maximu blood pressure value SYS is meaured. A first straight line (b) and a second straight line (d), which are formed of curves connecting the lower peak of each pressure pulse, cross at an intersection point (f), and on the basis of the point (f) a minimum blood pressure value DIA is measured. The intersection points (e) (f), correspond to the time when an artery blood vessel is squashed flat or when the push-pressure of the surface pressure sensor slightly exceeds the artery internal pressure. SYS and DIA thus properly indicate the absolute pressures in the artery.
